Model 2700AP Automation Controller Installation Guide Board Handling Precautions he module s printed circuit board contains electrostatic discharge sensitive (ESD) devices. Improper board handling could result in damage to the board. he following precautions are recommended when handling the board or before inserting it into the controller: Make sure you are grounded electrically by using a wrist strap connected to an electrically grounded workstation or by physically touching the controller case or something electrically connected to the controller case. Avoid touching the leads or contacts of the circuit board and handle the board by its edges only. ransport circuit boards in protective, anti-static bags, bins, or totes. Do not insert boards into materials such as plastic, polystyrene foam, clear plastic bags, bubble wrap, or plastic trays. 15

Control echnology Corporation Installing Modules into the Controller he controller accepts a variety of plug-in modules. he plug-in CP has its own slot and is not counted as part of the total number of slots in the controller. he module fits into one of the slots of the automation controller (Figure 5). Insert any combination of modules into the controller (subject to system limits) and install them in any order. his is possible because the controller s CP dynamically assigns such times as motor numbers, input numbers, and output numbers each time power is re-applied to the controller. hese numbers are assigned from left-to-right across the controller (from slot 1 to slot 10 in a model 2700AP-10). o install a module into the automation controller: Note Retain all hardware removed during this procedure. 1. Remove all AC and DC power, including any external supplies connected to the controller. 2. Locate an unused slot and remove two retaining screws from the top and bottom of its cover plate. 3. Slide the module into the slot and make sure that the circuit board slides into the nylon guides at the top and bottom of the controller case. Make sure that the card is oriented properly so that its labels are right-side-up. 4. Press the module firmly into the controller. Make sure that the module s faceplate is flush with the adjacent sheet metal surface. 5. Re-install two retaining screws in the top and bottom of the new module. 6.

Control echnology Corporation Connecting AC Power he Model 2700AP contains an internal power supply which provides two mutually-isolated voltages (+5 VDC and +24 VDC) for the operation of the controller. hree LED indicators are located on the CP: two for these voltages (I/O Supply and Logic Supply) and one to indicate if the controller is turned ON (Status). he controller s power supply requires AC power (either 120 VDC or 240 VAC nominal) for proper operation. Power is applied to the controller with a standard IEC-type power connector on the side of the controller. A S-standard three-prong power cord is provided with the controller for this purpose. he supply voltage required is determined by a voltage selector switch on the side of the unit (Figure 7). A fuse of the appropriate rating must also be installed in the fuse holder integral to the IEC-type connector (able 8). able 8. Fuse Ratings Voltage Range Fuse 120 VAC 100-132 2 A 240 VAC 200-264 1 A Figures 7 and 8 show the location of the voltage selector/fuse holder. he voltage selector/fuse holder is in a removable cartridge. o remove the voltage selector/fuse holder: 1. Insert a small flat head screwdriver into the slot and push the cartridge out. 2. Remove the voltage selector/fuse holder from the controller to change the voltage selection and to insert a fuse. he fuse holders are located along the side of the cartridge. Caution Do not connect an external supply with a voltage rating other than +24 V to this connector as potential incompatibilities may exist with other installed modules.

Often, when motors are first energized in heavy equipment, the stall currents that result can cause the voltage supplied to the step-down transformer to drop by as much as 50%. Because step-down transformers are ratio-metric devices, the voltage supplied to the controller drops proportionately, causing a potential system malfunction. he relatively light load imposed by the controller on the transformer secondary may result in excessive voltage and represents a potential hazard to the system. Neither type of transformer represents ideal protection against electrical noise. Interwinding capacitances can result in noise transference among windings and differential noise may still be electromagnetically coupled to the secondary. Adequate grounding of the controller is still critical to its proper performance. For more information, refer to he Importance of Proper Grounding. 19

Control echnology Corporation hese issues often point to the use of an independent power feed (120 or 240 VAC) for the controller and associated components. he resulting additional stability and design integrity are often well worth the slight additional cost. he Importance of Proper Grounding he controller is outfitted with an integral line filter to protect against electrical noise carried on the AC power line. his line filter, along with the shielding provided by the controller enclosure itself, depend on the presence of a good ground connection for effectiveness. his is normally accomplished by connecting the controller s power cord to a well-grounded outlet. As with any electronic equipment, the controller s ground should follow a direct, low-impedance path to the plant s power source. If possible, this path should not be shared by any machinery which injects a large amount of electrical noise into the ground. In instances where step-down or isolation transformers are being used to power the controller, the ground connection should still be made directly to the controller. For further consideration regarding noise protection, refer to echnical Note No. 26, Reducing Noise Susceptibility, which is available in the Customer Support area of our web site at www.ctc-control.com. he Controller s Power System he controller s power system provides two operating voltages that are electrically isolated from one another: +5 VDC supplies power to the controller s internal circuitry, the CP, and the logic-level circuitry on the various modules. +24 VDC available with a current capacity of up to 1.5 Amps (maximum). It supplies power to external control devices such as solenoid valves, relays and sensors. his power supply may also be used with some modules, supplying power to circuitry on the outbound side of any on-board isolation. For more information on 24 VDC usage, refer to a module s data sheet. he +5 V supply is not usually made available at any of the module connectors. Note Do not make any external connections to either the +5 V power supply or its common as an increased susceptibility to electrical noise may result. 20

Model 2700AP Automation Controller Installation Guide sing External Power Supplies Many of the modules available for this series of controllers allow the use of an external power supply for supplying power to actuators and other devices in place of using the controllers +24 V supply. he individual installation guides for these modules provide additional details. Figure 9. External VDC Connector Pin 1 - Backplane 24 VDC input + Pin 2 - Internal +24 VDC supply source - Pin 3 - Backplane and 24 VDC supply common External Power Supply 2700AP-15 It is possible to connect an external +24 V power supply (with a capacity not in excess of 10 Amps) to the controller s backplane, which takes the place of the controller s internal +24 V supply. A nylon, 3-pin connector is provided on the side of the controller for this purpose. his connector (as supplied by CC) is fitted with a mating plug that is wired with a jumper. he jumper carries +24 V from the internal power supply to the I/O power bus extending across the controller s backplane. Remove the jumper plug and use the connector to attach an external power supply to the I/O power bus and to the I/O common, pins 1 and 3. An extra mating connector with pins is included with each controller. You can also order a plug with a pigtail wires (Model 2885) from CC for this purpose. 21

Control echnology Corporation Status Light Description he status light on the Model 2700AP is used to indicate a software or hardware fault (Figure 10). hese faults are described below. Note After the controller is turned ON, the light is steady and green during the first second of operation. Software Fault Quickstep programs may produce software faults that are indicated by a periodic flashing light. hese faults occur when the 2703AP is unable to execute because an application problem exists within the Quickstep program. You can view the fault type by viewing the program status in Quickstep s monitoring utility, CCMon. Once a software fault occurs, the 2703AP is idle and all resources that can be set (outputs, etc.) remain in the state they were in before the fault occurred. Note You can program register 13009 to turn off a specific output when a software fault occurs. Refer to the Quick Reference Register Guide at www.ctc-control.com for more information. Hardware Fault Hardware faults are displayed as a steady green light and indicate that the internal watchdog timer has disabled the controller s CP. When this occurs, the controller s outputs are also disabled. ry clearing a hardware fault by cycling the power and/or downloading the same Quickstep program. If the fault continues, your controller may require repair. Contact our echnical Support representative for assistance. Figure 10.

Refer to echnote No. 30, ASCII Message ransmitting with CC Controllers, which is available in the Support section of our web site at www.ctc-control.com. Note For more information on data communications and the DLL functions required to communicate with the controller, refer to the CC 32-Bit Data Communications Functions Reference Guide, which is available in the Support area of our web site at www.ctc-control.com. RS-232 Connections (Single Port) Connections to the controller s RS-232 port are made through a modular jack on the controller (labelled COMM). his jack carries the receive signal, two commons (ground), and the transmit signal for the communications channel. he pin connection diagram (Figure 4) illustrates the wiring of the jack. Only the center four connectors of a six or eight conductor jack are used. RS-232 Connections (Dual Ports) he 2700AP can operate with dual RS-232 ports by adding the Model 2886 duplex adapter. Connect through one of the adapter s modular jacks (labeled COMM1 and COMM0). hese jacks carry receive and transmit signals for both ports as well as two commons (ground). Refer to Figure 4 for connection information. 23
